Question

the length, Breadth and height of cuboid are 10cm ,8cm , 6cm, respectively.find its surface area​

Answer 1

Answer:

Surface Area (TSA) of cuboid =

376 cm²

Step-by-step explanation:

Given -

Dimensions of cuboid :-

Length (l) = 10 cm

Breadth (b) = 8 cm

height (h) = 6 cm

to find -

Surface area (T.S.A.) of cuboid

solution -

T. S. A. of cuboid = 2(lb+bh+lh)

= 2 × {(10×8)+(8×6)+(10×6)} cm²

= 2×(80+48+60) cm²

= 2×188 cm²

= 376 cm²

Hence surface area of cuboid = 376 cm².

extra information -

Total Surface Area (TSA) of cuboid = 2(lb+bh+lh)

Lateral Surface Area (LSA) of cuboid = 2(lb+bh) or 2(l+b)h

TSA of cube = 6a²

LSA of cube = 4a²

in this exercise you have to use these formulas.

hope it helps.
